"his invention relates to non-corrosive cleanout fittings, its objectbeing to provide a cleanout fitting or the like in which both the plugand the element to be sealed are formed of iron and so arranged that theplug iis threaded in a lead'seat to secure a tight In plumbing fixturesand the like a brass plug is usually threaded in an iron fitting to loreduce the liability of the plug rusting ast but brass plugs are muchmore expensive than iron and are only partially effective as it is quiteoften a diflicult matter to unscrew brass plugs after they have been inplace for any length of time. By the construction as hereinafterdescribed it is possible to use an iron plug without liability of theplug rusting in place.

he principal feature of the invention is in the provision of the fittingto receive the plug having an annular space for lead caulking forcedthereinto subsequent to the positioning of the plug and thereafterremaining in place permitting threading of the plug in or out ofposition.

' A further feature of the invention is in the provisionin a plumbinfitting of a supfport for a sealing plug of suc character and orm as topermit ready removal whereby the fitting may be used with or without aplug.

These various objects and the several novel features of the inventionare herein-- after more fully described and claimed and the referredform of a non-corrosive cleanout iitting embodying my invention is shownin the accompanying drawings in which Fig. 1 is a cross section of aplumbing fixture showing my improved construction.

Fig. 2 is an enlarged vertical section of a portion of an iron ttingshowing the plug m place.

It is tobe understoodthat this non-corrosive fitting is utilizable invarious ways where a plug is required to be used in sealing an apertureand in which the non-corrodible characteristic is desirable. In thedrawing I have shown a plumbing structure known as a stack base. This isto be understood as illustrative of only one form of structure in whichmy invention may be embodied or associated and the descri tion of thistype of structure will enable ot ers to utilize the same with anyelement especially plumbing fittings with which it may be advantageouslyused.

In Fig. 2 I have shown an enlarged section of a lumbing fitting 1 whichis of cast iron and as the general form of a hub. At its open end thereis rovided an integral internal flange 2 of sma l depth and below thesaid flange and in spaced relation therewith I provide a second internalflange 3 providing a central threaded aperture to receive an iron plug4. The threads of this flange 3 have a loose fit in the threads of thelug for the reason that both parts being 0 iron rust may accumulate inthe said threads. By making the threadsbetween the plug andthe flange 3a loose fit and by forming the flange with only one or two threads theossibility of the plug rustin in place is re need to a minimum. The p nbeing positioned in the flange 3 as suggeste in Flg. 2, there is anannular chamber 5 provided about the body of the plug and between theflanges 2 and 3. The flan e 2 has an aperture materiall larger than t ediameter of the plug provi 'ng a throat 6 to the chamber 5 andpermitting introduction of lead caulkin which, subsequent to thepositioning of t e plug as shown, is forced to place. By cau ing thislead in place aboutthe threaded body of the plug the lead is made toconform to the threads and thus there is provided a threaded aperture inthe lead caulking as will be more clearly understood. This plug is alsopreferably of tapered form so that if there is a slight leakage at anytime the plug may be screwed in to greater depth and due to its ta ered'form will tend to seal the o ening, an further the lead caulking may emore tightly hammered about the plug at any time to insure the sealingof the interior of the member to which the plug is applied.

In Fig. 1 I have shown a stack base 7. With this type of structure thereare two hubs provided integral with the fitting as indicated at 8 and 9,the hub 9 correspondin in all general respects to the form of t estructure shown in Fig. 2. Also (not here shown) it is to be understoodthat prior to erection in a building both these hubs are provided withthe flange 3. In erecting the stack base it is sometimes necessary thatthe stack indicated at 11 be used with a hub 8 or with the hub 9depending upon the location of the stack in relation to the wall of thebuilding. In the event it is to be used with the hub 8, as in the caseillustrated, the flange 3 is broken from position in that hub. For thispurpose the flange 3 atits point of connection with the wall of the hubis comparatively thin enabling it to be readily removed by a'hammer orlike instrument whereupon the stack 11 may be introduced into the hub 8as shown in Fig. 1 providing a space between the inner edge of theflange 2 and the stack in which caulking 13 may be introduced as isusual. In the illustration the other hub 9 is provided with a plug asshown and the lead packing 10 introduced thereinto as above described.In case it is necessary to use the stack 11 with the hub 9 it will bereadily understood that in such instances the flange 3 of the hub 9would be removed and that in the hub 8 remain in place to receive theplug.

From the foregoing descri tion it will become evident that the metalange 3 integral with the body of the hub or fitting with which 7 theplug is to be used is only provided for the purpose of supporting theplug during the caulking operation and to provide a base or support forthe caulking and, due to the ,looseness of the threads in the member 3and the plug, the threads depended upon to seal the aperture are in thelead member. Therefore, the plug 4 will not become rusted in place andis always readily removable and maintains a tight oint and, if bycontinued removal or insertion of the plug the threads of the leadmember become deformed to an extent permitting leakage, the lead by theuse of a caulking implement can be hammered to tight engagement with theplug restoring the parts to original condition.

It is believed evident from the foregoing description that myconstruction is less expensive than former constructions utilizing brassplugs, is equally eflicient and is practically indestructible eventhough comparatively soft material is used as the threaded member toreceive the plug.

Having thus briefly described my invention, what I claim and desire tosecure by Letters Patent of the United States isv 1. In a device of thecharacter described,

an iron plumbing fitting having a hub, an internal flange at the openend of the hub providing a central aperture, a second integral flangewithin the hub spaced from the first flange and having a centralthreaded aperture less in diameter than the aperture pro vided by thefirst flange, a threaded iron plug of tapered form loosely supported inthe threaded aperture of the second flange a lead member provided in thechamber 6- tween the flanges about the ilug in engagement with thethreads of the p ug and providing a seat therefor, the said secondflange having a weakened portion permittin its ready severance from thebody of the hu substantially as and for the pur ose described.

2. In a device 0 the character described, an iron lumbing fitting havingan open ended hub or introduction of an element thereinto, an integralflange below the open end of the hub having a central threaded apertureless in diameter than the said open end of the hub, a threaded iron plugloosel supported in the threaded aperture of the ange, a ring ofcomparatively soft non-corrodible material positioned in the spacewithin the hub about the plug and in tight engagement with the threadsthereof providing a seat therefor, the flange having a weakened portionadjacent its point of connection with %he hub permitting its readyseverance thererom.

3. In a device of the character described, an iron plumbing fittinghaving a hub, an internal flange at the open end of the hub providing acentral aperture, a second internal flange spaced from the first flangeand having a'central threaded aperture less in diameter than theaperture provided by the first flange and the two flanges providinganannular recess or chamber therebetween, a threaded iron member oftapered form for threaded relation with the threaded aperture of thesecond flange, a comparatively soft non-corrodible material positionedin the annular recess and in tight engagement with the threads of thetapered member, the threaded flange being severable from the hub andproviding means by which the non-corrodible material is caused to bepacked tightly in the recess and against the second flange by the act ofthe threading of the tapered member 1iinto the threaded aperture of thesecond ange.

In testimony whereof I sign this specifica-
